C++ size of data types
WebOct 3, 2011 · C++ is a language for library writing*, and allowing the author to be as general as possible is one of its key strengths. Rather than prescribing the standard containers to use any particular data type, the more general approach is to decree that each container expose a size_type member type. This allows for greater flexibility and genericity. WebData types define the a type of data variable the a variable data can hold. For example, an integer variable can hold integer data, and a character type variable can hold character …
